6 Claims.

The device of this inventionrelates to the hair dressing art i-n general, and in particular to that division of the art which has for its purpose the development of ringlets of hair commonly termed pin curls, for the reason, that after formation the ringlets or curls are secured in place by means of hair-pins until the curl assumes a fixed contour, or the curl may bev Worn withits supporting hair-pins in position depending only upon the choice of the party concerned.

Ordinarily pin curls are formed with the fingers and after formation are secured in position by hair-pins, and while this method is satisfactory if performed' by a hair-dresser who is skilled in the art, nevertheless it is most unsatisfactory when one tries to dress her own hair as falls to the lot of most people.

Being aware of the limitations and diiculty in forming pin curls upon ones own head, I have contrived to providemeans to facilitate this form of work.

' Therefore, it is a prime object of the-'present invention to provide a simple and easily used device to give strandsof hair ring-like form and while inv this position to apply a hair-pin thereto in such manner as to retain the ringlet after removal of the accessory used in its formation.

`Another' object of the invention is to provide a pin curl accessory which may be used to clamp the near outer ends of strands of hair and which isV thereafter adapted to be rotated whereby the hair is wound upon the outerv side of the accessory to form a curl or ring, the accessory being so formed as to admit of insertion ofhair-pins to clasp the curl thus formed at several places whereby its shape is retained after withdrawal of the accessory.

A further object of the invention is to provide a device which is adapted to clamp strands of hair between half portions thereof and which is then turned or rotated around the longitudinal axis ofthe device whereby the'hair is wound upon the outer side of the device to form a curl or ring, the device being formedV with slots, in the end adjacent the ring of hair, whereby hair-pins may be inserted across the diameter of the device to clasp and hold the ring orcurl thus formed after which the device is finger pressed to release the hair from their clamped position.

A still further object of the invention is to provide a pin curl forming device which is'simple in construction, low cost, rugged', and reliable and which iseasily used.

Otherobjects, features, andA advantages of the invention may be apparent-frommeaccompanying drawing, the specification, and the subioined claims. l f

Figure 1-2 is a view illustrative of a curll formed withthe device ofV this invention, both the device and temporarily used hair-pins being removed to better show the form of the curl which is symmetrical in all detail.

The device of this invention I8, as shown in Figure 1, comprises the half-portionsV 20 and 22 which` are complementary to each other and which are joined by meansof a pintle 24.

The portion 20 is rst formed as a blank punching die stamped from suitable sheet metal, and after being placed in a forming' die is bent trans- Versely tov for-m a channel-shaped member that is` approximately semi-circular in cross section with its sides 28 and 3U lying substantially 180 degrees apart in a uniform degree of curvature. The product thus formed isL best illustratedL in Figs. v3 and?. 4. Elongated slots 32y arepunched from the stock 26 at the time the blank is irst punched therefrom. Openings 34 are formed in the blank at the time of its formation and form bearing points for the Dintle 24.

The half-portion 22 is in part formed in the same manner as the portion 20, that is, it is formed with a semi-circular end 36 having elongated slots 38 and an opening 40 which is complementary to the openings 34 and is likewise adapted to form bearing points for the pintle 24 which may be either tubular or solid for its sole purpose is to form a pivotal connection between the half-portions and 22. However the portion 22 essentially distinguishes from the portion 20 in that it is formed with an extension 42 which rises above the plane of the semi-circular v 44h is coincidental with the half-portion 22 and reference to Figures 1 and 2 will show that these lines or structural edges are intended to be brought into alignment and hence formv stops lagainst the action of spring 46 which presses outwardly against the finger grip ends 48 and 49, however, the extension 42 as shown in dotted lines in Figure 1, also forms a stop against pressure of the spring 46 and therefore eliminates any tendency for they line 44a and 4419 to slip or move laterally and hence be brought into lapped relation, for as will be shown in the description of operation it is essential that these lines or edges be brought into pressure contact to clamp strands of hair which are temporarily held therebetween as shown in Figure 10 at 50.

The following matter forms a description of use in forming a pin curl with the device of the present invention. l

With the device assembled as shown in Figure 1, it is only necessary to apply inwardly directed pressure upon the finger grip ends 48 and 49 to spread the clamping ends 2| and 23 which fulcrum upon the pintle 24, thereby enabling insertion of the free ends 53 of strands of hair 52. Thereafter the device I8 is rotated around its longitudinal axis which is substantially parallel to the scalp, thereby winding the hair 52 around the exterior surface of the device so that it builds up into an annular ring-shaped roll as shown in Figure 10.

The device is now upended with its longitudinal axis pointing toward the head and with the circular forward end of the device resting gently against the scalp. By means of pressure of the thumb and finger, the strand or lock of hair previously wound upon the forward portion of the device is now pushed to the forward end of the device so as to occupy a position immediately against and parallel with the adjacent portion of the scalp, thereby forming an annular or ringshaped body of hair, and the deviceis now rotated so as to more tightly wind the annular body of hair thereupon.

The legs of a hairpin which normally bear directly against each other as a result of the resiliency of the metal of which the hairpin is formed, are now separated a slight distance and said separated legs are passed through two ofthe diametrically opposite slots in the forward portions of the jaws of the device and said pin manipulated so as to receive between them the ringshaped body of hair and when the legs of the hairpin are released, the circle of hair is gripped at two oppositely disposed points and with said body of hair and the hairpin lying substantially flat against the head.

To further grip and hold the annular body of hair in proper position, a second hairpin formed of resilient metal is inserted through the other two diametrically arranged slots in the forward portion of the device so as to grip the ringshaped body of hair at points ninety degrees from the points engaged by the first inserted pin, and thus the coiled body of hair is gripped at fourlpoints ninety degrees apart as illustrated in Fig. 11.

The forward end of the device is now withdrawn from the ring-shaped body of hair which is retained in its annular form by the clamping effect of the legs of the hairpins and the latter are permitted vto remain on the body of hair until the same becomes set, after which the pins are removed, leaving a perfectly formed ringlet or pin curl.

If the hair has been treated with certain hair dressings the curl 54" thus formed will naturally last a greater length of time because of stiffness imparted thereto by the dressing, otherwise the curl will last through a period proportional to natural susceptibility of the hair to curling.

Thus it willbe seen that I have provided a pin curl forming device that is relatively simple in construction, inexpensive of manufacture and very effective in performing the functions for which it is intended.

The particularly desirable and advantageous feature of my improved pin curler is the provision of a plurality of pairs of diametrically arranged slots whichextend from thel forward ends of the jaws of the device a short distance rearwardly through those portions of the jaws upon which the strand of hair that is to be curled, is wound and which slots enable the legs of resilient hairpins to be inserted through the forward portion of the curling device to grip the curled body of hair and firmly retain the same in its desired form while becoming set and further, said slots permitting the curling device to be readily withdrawn without disturbing the curl of hair and the hairpins that are applied thereto.

In conclusion, it may be stated as being obvious that various and sundry changes and modifica- .tions may be effected in practicing the invention in departure from the showing of the drawing and description as given, without however, departing from the true spirit of the invention as defined by the scope of the appended claims.
